Narrow-band interference (NBI) is a critical issue for synthetic aperture radar (SAR), in which the imaging quality can be degraded severely. To suppress NBI effectively, a novel interference suppression algorithm using robust principal component analysis (RPCA) based signal separation in time–frequency domain is proposed. The RPCA algorithm is introduced for signal separation in the time–frequency...
A novel moving target imaging algorithm is proposed based on coherently integrated cubic phase function (CICPF) for synthetic aperture radar (SAR) system. The CICPF algorithm can solve the identifiability problem caused by cubic phase function (CPF) when dealing with multicomponent signals. Moreover, the CICPF algorithm can estimate the parameters of multicomponent signals without searching procedures...
